Dust Hazard Analysis Dust Hazard Analysis. A Dust Hazard Analysis or DHA is a process hazard analysis focusing on combustible dust. The DHA provides a formal document to determine where hazards exists, what safeguards are in place, and what safeguards are needed. The DHA process is now a requirement in many of the NFPA combustible dust standards including NFPA 652.

Occupational Safety and Health Administration Occupational Safety & Health Administration. Combustible Dust: An Explosion Hazard. Any combustible material can burn rapidly when in a finely divided form. If such a dust is suspended in air in the right concentration, under certain conditions, it can become explosible. Even materials that do not burn in larger pieces (such as aluminum or iron), given the proper conditions, can be explosible in dust form. The force from such an explosion can cause employee deaths, injuries, and destruction of entire buildings.

Occupational Safety and Health Administration Wood dust becomes a potential health problem when wood particles from processes such as sanding and cutting become airborne. Breathing these particles may cause allergic respiratory symptoms, mucosal and non-allergic respiratory symptoms, and cancer. The extent of these hazards and the associated wood types have not been clearly established.

NSSL Research: Damaging Winds Predicting Damaging Winds. NSSL developed an algorithm in collaboration with Arizona's Salt River Project (SRP) to alert the power company of the potential for a dust storm called a haboob. A haboob is a wall of dust that is pushed out along the ground from a thunderstorm downdraft at high speeds.

Hazard analysis Preliminary risk levels can be provided in the hazard analysis. The validation, more precise prediction (verification) and acceptance of risk is determined in the Risk assessment (analysis). The main goal of both is to provide the best selection of means of controlling or eliminating the risk.

- Adverse Effects. Although non toxic, aluminum sulfate dust can cause irritation to the eyes, nose, mouth and throat if inhaled. Flushing with large amounts of water will ease uncomfortable symptoms of exposure. When ingested in large amounts it causes gastric irritation, nausea, vomiting and diarrhea.

- Deltana SPDP278, Dust Proof Door Bolt Strike. This is an adjustable height dust proof door bolt strike. Most often used on installed on the door threshold for a surface mounted or flush bolt, to prevent the accumulation of debris in the bolt strike hole. This strike adds more security to door bolts.

- A process hazard analysis (PHA), or evaluation, is one of the most important elements of the process safety management program. A PHA is an organized and systematic effort to identify and analyze the significance of potential hazards associated with the processing or handling of highly hazardous chemicals.

- If the wipe is lighter than the picture on the card, the area is considered to be clean. Note: This is a controversial part of the regulation. Standard procedure after most lead jobs is to hire a 3rd-party State-Certified Lead Inspector to take (clearance) dust samples for laboratory evaluation. However, as of today, the RRP rule does not require 3rd-party testing of any kind.

Job Safety Analysis Job safety analysis. A job safety analysis (JSA) is a procedure which helps integrate accepted safety and health principles and practices into a particular task or job operation. In a JSA, each basic step of the job is to identify potential hazards and to recommend the safest way to do the job. Other terms used to describe this procedure are job hazard analysis (JHA) and job hazard breakdown.
